Hello i´ve tried to do the same like in this video from Colin O´Flynn: https://www.youtube.com/watch?v=dVkCNiM0PL8
on my own target. I´ve implemented a UART program with the same for loops, variables and outputs. I use simple jumper wires for the VCC glitch pin and GND. My target runs at 48MHz and i´ve tried to use different frequency´s for the Chip Whisperer (48MHz, 96MHz, 100MHz), but i think this has no influence for this simple glitch.
When i use a repeat value of 48 my target reboots and when i use values lower than 48 nothing happens. The output values do not change. I also tried with High, Low and High&Low Power Glitch, only the values for repeat change when the target reboots.
What can i do to get successes? Remove Capacitors near the Core Voltage? Or is this a sign that this target cannot be glitchted?
Thanks and best regards Rik
